To all whom it may concern:

Be it known that I, BUTLER AMES, a citi zen of the United States,residing at Lowell,

in the county of Middlesex 'and State of Massachusetts,'have inventedcertain new and useful Improvements in Razors, of which the followingis` a specification, ref- .erence being had thereinto the accompanyingdrawing.

-in` attaining this purpose.

that it doesawaywith My invention relates particularly to means forremovably securing a metallic'blade of an instrument, say a razorto itssupport or handle; and may be said to 'reside ina suitable structuremaking use 'of magnetism The advantagesV of such a structure are 'screwconnections 'formerly employed, the

parts great ease and speed; there are no small parts to bedropped andlos-t; and the mag; netic lines of force, whilel the blade is inposition, iiow through-,it with a beneficial effect of improving thecutting 'qualities of 4 the blade. l

In the drawings illustrating the principlek of my invention and the bestmode now knowny to me of embodying the samein operative structure,

Figure 1 is anelevation partly in section. of a razor embracing myinvention;

Fig. 2 shows an end view of the same;

Fig. 3 is a plan of it;

Fig. 4 illustrates anA enlarged detail, one

pole piece of a magnet provided with cooperating parts for attaining theobject of my invent1on;, and Fig. .5'is a perspective view showing themanner of assembling or demounting the razor blade and its coactingmembers.

A horseshoe magnet 1 of such size as to be conveniently grasped inthe.hand, has

legs 2 which are circular in crossV section,

say one-quarterof an inch in diameter, and

one` inch a art. They are made of magnet steel, and t en hardened thedesired amount, but before they piece of the magnet, in thedirection ofits length, has a threaded hole provided for the receptionl of ametallic {iatheaded retaining screw 3 later to'be described. A ring 4 ofsoft iron having the same diameter as the legs .of the magnet,- abutsthe ,end of each leg, while a cross bar 5 ofbrass or other non-magneticmaterial provided with safety V while th the necessity of using may beassembled or'talren apart with,

from'the leg7 pin, capan are so hardened, each pole ingers, is mountedupon, and unites these end portions of the magnet; the under and uppersides of the safety bar being recessed to receive respectively the ringsand the` iiatheaded screws 3; the tops of the heads being flush with thetop surface of the safety bar. Permanently fixed in the longitudinalaxis of each screw 1s a round nosed guide and lock pin. 6, whichnecessitates having Spanner holes in the screw head'.` A thinrectangular double razor blade y7 with two holes registers with theguide and lock pins 6; as does a lock cap 8 of soft iron, the cap beingnarrower 'and longer than the blade, y e blade-is narrower than thesafety bar with its protecting fingers 5*. In short, the 'aboveapparatus described is a safety razor provided with a Vmagiieticallyrather than'mechanically secured la It will be observed that themagnet,rings, screws, guide pins and bar are for all practical purposespermanently assembled for use and form a unitary structure; while thelock cap and -blade are manually separable. y When the parts of thecomplete magnet are in operative position, offorce flow from one pole ofthe magnet to the other, that is to say, for example, through the ring,screw, guide razor blade,vand the guide pin, screw,`r1ng.of the leg. AThe guide pins rigidly revent lateral and longitudinal movement o theblade and cap with relation to the legs of themagnet, vwhile the stren hof the `magnetic field is suiiicient to hol the blades in' operativeposition against the'safety bar. Y

.If the blade isgto be removed, the ends of the cap are gras ed betweenthe thumb and first finger, an
